GreenFin

Pelletized fish feed built on duckweed protein grown at our own ponds. Three lines, all made in pilot batches.

Pack concepts, modelled in 3D. Production packaging may differ.

GreenFin Carp Polyculture

For ponds stocking several carp species together, such as rohu, mrigal and grass carp.

  • Pilot batch
  • In university feeding trials

GreenFin Tilapia

For tilapia ponds and tanks.

  • Pilot batch
  • In university feeding trials

GreenFin Ornamental

For aquarium and ornamental fish, in a smaller pack.

  • Pilot batch

  • Duckweed protein

    Grown on our lined raceways near Islamabad, then dried to a meal.

    A physical fact about our ponds and equipment.

  • ~31% crude protein

    As-is, in one recent pilot batch. Further testing is underway.

    Measured by a third-party laboratory on a specific sample.

  • No fishmeal. No soy.

    The formulations in our university feeding trials use neither fishmeal nor soybean meal.

Pakistan imported more than two million tonnes of soybeans in 2024–25, most of it for animal feed. That protein is priced in dollars before it reaches a single pond. Duckweed grows here, on water, and can double in days.

  1. 01

    Raceway pond

    Lined with HDPE. We run two.

  2. 02

    Central baffle

    Splits the pond into a loop so the water keeps circulating.

  3. 03

    Paddlewheel

    Moves the water gently around the loop.

  4. 04

    Solar borewell

    Supplies fresh water, powered by the sun.

  5. 05

    Shade net

    Added over both raceways in 2026 against heat and storms.

    Mother-culture ponds

    Back-up stock for restocking the raceways.

Process

From pond to pellet

  1. Duckweed fronds covering the surface of a raceway, seen from above

    Grow

    Duckweed grows on the surface of shallow raceways lined with HDPE. A paddlewheel keeps the water moving; a solar-powered borewell supplies it.

    2–3 days

    for a healthy duckweed surface to double, in good conditions

  2. A harvest scoop lifting duckweed from the raceway

    Harvest

    We harvest from the surface and leave enough cover to regrow. Each pond is checked for pH, water temperature, plant colour and pests.

    ~90%

    of fresh duckweed's weight is water

  3. A pile of dried duckweed meal

    Dry

    Fresh duckweed is mostly water, so it can't travel far or keep for long. Drying it to a meal is what turns a pond crop into a feed ingredient.

    35–40%

    crude protein in dried duckweed, dry basis, across tested batches

    Measured by a third-party laboratory on a specific sample.
  4. GreenFin feed pellets

    Pellet

    The meal is formulated and pressed into GreenFin pellets, a form that can be stored and transported. Durability and shelf life are still being tested.

    ~31%

    crude protein, as-is, in one recent pilot batch

    Measured by a third-party laboratory on a specific sample.

Already have ponds or a dam?

We work with existing fish farms, pond owners and dam operators to raise output with locally produced feed, technical expertise and better production management.

  1. You bring the water

    Ponds, a dam or a reservoir, and the people who run them.

  2. We bring feed and know-how

    GreenFin, feeding and stocking plans, water-quality management and support on site.

  3. We measure it together

    Growth, survival and feed use, recorded and shared with you.

Research network

Tested by universities, from Rawalpindi to Jamshoro.

GreenFin is in feeding trials with 6 university partners across Punjab and Sindh. Each trial is listed with its species and status; results are published once they have been analysed.
